;^Q BOTANY. 



Caltha leptosepala, D C. stems (3'-l° Mgh) erect, 1-flowered ; leaves 

 radical, ovate-cordate, obscurely crenate; carpels beaked with the short 

 recurved style; sepals white, or tinged with blue.— Subalpine swamps, 

 Colorado to California and Washington Territory. Found in the East Hum- 

 boldt and Clover Mountains, Nevada, and in the Wahsatch, Utah ; 9-10,000 

 feet altitude ; July-September. (31.) 



Teollius laxus, Salisb. Sepals dull greenish-white or yellowish. New 

 Hampshire to Delaware and Michigan, and on the eastern slope of the Rocky 

 Mountains, from Colorado to latitude 55°. Uinta Mountains, Utah ; 9,000 

 feet altitude ; July, August. (32.) 



Aquilegia Canadensis, L., Var. Formosa, Torr. Tall, 2-3° high, 

 nearly naked above, the hmb of the petals 1-2" long, the spurs never greatly 

 exceeding the reflexed sepals ; styles shorter than the stamens.— The parts 

 of the flower of this prevalent and perhaps distinct western Aquilegia are so 

 variable that A. truncata, Fisch. & Mey., {A. Californica, Lindl. and A. 

 eximia, Van Houtte,) can with difficulty be separated from it. California to 

 Alaska; not unfrequent on mountain streams in Nevada, at an elevation of 

 6-7,000 feet, but not seen in Utah. June-September. (33.) 



A subalpine form has the stem nearly simple, few-flowered ; uppermost 

 leaflets entire, oblong or oval ; sepals oval, equaling or exceeding the spurs. 

 East Humboldt Mountains, Nevada; 8-9,000 feet; July, August. (34.) 



Aquilegia flavescens. Spurs more or less incurved and tipped, shorter 

 than the spreading or reflexed oval or oblong-ovate sepals ; limb large (3-4" 

 long) and dilated ; styles nearly equaling the long exserted stamens. — 2—3° 

 high ; glabrous, with the carpels and peduncles pubescent ; flowers yellow, 

 the sepals (4-1' long) frequently tinged with scarlet. Wahsatch and Uinta 

 Mountains, Utah ; 5-7,000 feet altitude ; May-July. It has been collected 

 also by Lyall on the the Oregon boundary, and by Bourgeau in the Rocky Moun- 

 tains, and referred provisionally to A. Canadensis. A comparison of a large 

 number of specimens leaves no doubt that it is distinct. (35.) A more alpine 

 form has much smaller leaves and flowers, with the stem sometimes subpu- ' 

 bescent. (36.) 



Aquilegia ceeulea, James. Spurs straight, very slender, 2' long ; 

 sepals rhomboid-ovate, longer than the limb ; stamens and styles shorter than 

 the corolla. — Stem 2° high ; glabrous, few-flowered ; flowers 3' in diameter, 

 white in all the specimens of the collection or with the sepals very lightly tinged
